Welcome to our forum, from one of the guys in an MFM polyamorous (polyfidelitous, in our case) vee. I think you have a very good attitude going into this, and are willing to be honest with yourself.
Although I'm technically "ex-Christian," I still have good memories from my time in the church, and know well that a good many Christians are indeed Christ-like. So you haven't lost any points with me in that area, I think you should follow your heart when it comes to what you believe.
I can relate to you about needing a good degree of emotional intimacy before physical intimacy can be enjoyed. I suppose I could get into the physical without the emotional, but I'd much rather have both.
I'm glad you've found us, have signed up and posted. Keep on exploring our site, and post any thoughts or questions that may come to your mind.
With regards and well wishes,
Love means never having to say, "Put down that meat cleaver!"
